Abstract：Objective To explore the application value of American College of Radiology (ACR) thyroid imaging reporting and data system (TI-RADS) in diagnosising of thyroid nodules. Methods A total of 110 patients with thyroid nodules (118 nodules) who received ultrasound examination and obtained pathological results in the Department of Ultrasound, Daxing Teaching Hospital of Capital Medical University from January to December 2019 were selected as the research objects. Two-dimensional ultrasonographic characteristics of 118 nodules were observed, according to ACR TI-RADS classification criteria, the ACR TI-RADS classification was counted and the receiver operating characteristic (ROC) curve was drawn to observe its diagnostic value for nodules ≥1 cm and < 1 cm. Results Of the 118 nodules, 73 were benign and 45 were malignant. All (100%) of 45 malignant nodules were solid; 43 nodules showed low echo or very low echo, and only 2 nodules showed isechoic; 31 (68.9%) nodules showed aspect ratio > 1; 30 nodules had irregular margins, and 3 nodules had extrinsic thyroid invasion; 22 nodules with punctal calcification and 3 nodules with extensive calcification. Among 118 thyroid nodules, 26 nodules were TI-RADS 2; 7 nodules was TI-RADS 3; 32 nodules was TI-RADS 4; 53 nodules was TI-RADS 5. The critical value of ACR TI-RADS for benign and malignant nodules ≥1 cm was 6.5 points, the area under the curve was 0.935, and the sensitivity and specificity were 88.9% and 87.0%; The critical value of ACR TI-RADS classification for benign and malignant nodules < 1 cm was 6.5 points, the area under the curve was 0.725, and the sensitivity and specificity were 92.6% and 40.7%. Conclusion ACR TI-RADS classification has high accuracy in benign and malignant diagnosis of ≥1 cm thyroid nodule, and medium accuracy in diagnosis of < 1 cm thyroid nodule, which should be referred to in clinical decision making.
